To Evaluate the clinical characteristics of childhood-onset systemic lupus erythemoatosus (SLE) and analyse the factors related to outcome of renal function in lupus nephritis, we reviewed medical records of 18 cases of SLF diagnosed at the Department of Pediatrics. Pusan National University Hospital from January 1981 to December 1990. The results were as follow: 1)Male to female ratio was 1:2.6. 2) Nephropathy was the most common initial impression, and 8 cases were diagnosed as SLE at first. 3) The clinical menifestation. was ANA (+), malar rash, renal disorder, hematologic disorder in frequency. 4) Diffuse proliferative lupus nephritis was the most common in renal histopathologic studies. 5) Among the follow-up cases, active lupus was 39%, remission was 28%. 6) As factors related to outcome of lupus nephrits were, hypertension and proteinuria were siginificant statistically.

BACKGROUND: Acute idiopathic thrombocytopenic purpura(ITP) in children has a low morbidity and mortality, and most of cases are self limited illness. But some of them are not responsive to treatment and finally progress to chronic disease. The purpose of this study is to evaluate the factors which influence the outcome in childhood idiopathic thrombocytopenic purpura. METHOD: From January 1990 to December 1995, patients with ITP who were admitted to the Pediatric department of Pusan National University Hospital were divided into acute and chronic form depending on whether the platelet count had returned to normal(150 x 10(9)/1) by six months after diagnosis. Between two groups, the clinical and laboratory characteristics, response to treatment were compared. RESULT: 1) Out of 55 patients with ITP, 36 cases(65.5%) were acute and 19 cases(34.5%) were chronic ITP. 2) Sex, previous viral infection history, clinical manifestations were not significantly different between two groups, but the chronic ITP was rare in less than 1 year of age. 3) The duration of symptoms over >2 weeks at presentation was strongly predictive of chronic ITP. 4) Most of chronic disease (87.5%) showed platelet counts below 150 x 10(9)/1 at 28 days after diagnosis as compared with acute disease(25.0%). 5) Among 19 cases of chronic disease, 6 cases responded completely to treatment, but 11 cases(57.9%) did not respond to any treatments, 2 cases improved spontaneously. CONCLUSION: A history of symptoms over 2 weeks at presentation and platelet counts below 150 x 10(9)/1 at 28 days after diagnosis were strong predictors of chronic ITP in children.

PURPOSE: We wanted to determine the usefulness of computed tomography (CT) for patients with clinically-suspected but equivocal acute appendicitis, and we wanted to evaluate the differences of the sensitivity and specificity of CT according to the period of time from onset of the signs and symptoms to the performance of CT. METHODS: A retrospective study was done on 273 patients who visited our hospital for acute abdominal pain from Jan. 2003 to Dec. 2005, and they could not be excluded as suffering from acute appendicitis by their symptoms nor signs. RESULTS: Forty-three (15.8%) of the 273 patients did not undergo operation because their condition was not diagnosed as acute appendicitis and 190 patients were diagnosed as acute appendicitis by CT. The other 40 patients underwent diagnostic laparotomy because acute appendicitis could not be confirmed and any other diagnosis could not be made. The patients were classified into 6 groups according to the period of time from the onset of symptoms and signs to the performance of CT. The sensitivity of CT after 48 hours was statistically significantly increased as compared to performing CT before 48 hours (92.3% vs. 75.8%, respectively; P=0.023). CONCLUSION: Forty-three (15.8%) of the patients with clinically- suspected but equivocal acute appendicitis avoided unnecessary laparotomy by undergoing CT. The sensitivity was increased for diagnosing acute appendicitis by CT when it was performed after 48 hours from the onset of symptoms and signs, but caution may be needed during interpretation because of the false positives (2 patients;4.7%) could due to secondary change of other diseases

PURPOSE:Obesity is a common complication in children who were surgically treated for craniopharyngioma. We analysed body composition, metabolic parameters and evaluated for correlation between adiponectin and metabolic parameters in children who were surgically treated for craniopharyngioma. METHODS:Sixteen patients with craniopharyngioma (9 males, 7 females) were included in this study (patient group). The data of patient group were compared to those of children who visited the clinic for normal short stature with appropriate gestational age (14 males, 4 females) (control group). Height SDS, weight SDS, BMI were calculated. Total body fat, abdominal fat distribution were measured by bioelectrical impedance analysis. Plasma levels of total cholesterol, HDL-cholesterol, triglycerides, adiponectin, and insulin were measured after overnight fasting. The degree of insulin resistance was calculated by HOMA-IR. RESULTS:Four of 16 patients were obese. and three were overweight. Patient group had higher total body fat percentage (27.5+/-6.8 vs 17.6+/-6.8, P=0.01), triglycerides (207.9+/-241.6 vs 76.7+/-30.8, P=0.001), lower HDL-cholesterol (37.5+/-14.6 vs 61.4+/-15.4, P=0.000) and adiponectin levels (7.1+/-4.2 vs 10.7+/-4.3, P=0.012). Adiponectin levels were correlated negatively with total body fat percentage (r=-0.631, P= 0.009), abdominal fat distribution (r=-0.547, P=0.03), triglycerides (r=-0.518, P=0.04), insulin (r=-0.525, P=0.037) and correlated positively with HDL-cholesterol (r=0.572, P=0.021). CONCLUSION: These results suggest that children who were surgically treated for craniopharyngioma, had tendency to develop obesity, dyslipidemia and Insulin resistance. Therefore, patients who were surgically treated, should be closely monitored to minimize the effect of metabolic syndrome on their health and well being.

In the therapeutic or the nutritional aspects, Zn2+ has been used as a supplement in a variety of drugs. Most of divalent or trivalent cations affect ion channels in the cell membranes of various organs. In particular, Zn2+ has been regarded as a potassium (K+) channel blocker in the field of electrophysiology. ATP-sensitive K+ (KATP) channel, which is a kind of inward rectifier K+ channel, resides in the cell membrane of pancreatic beta cells and plays an important role in glucose-induced insulin secretion. The glucose increases intracellular ATP concentration, and this inhibits KATP channels. The inhibition of KATP channels activity depolarizes the cell, and subsequently, insulin is released by Ca2+ influx through the voltage- gated Ca2+ channels. Here, we demonstrate that KATP channels in the pancreatic beta cells are also the targets of extracellular Zn2+ blockade and its blockade is dependent on intracellular ATP concentration. This may be a compensatory mechanism preventing the oversecretion of insulin from the Pancreatic beta cells triggered by Zn2+ intake in a physiologically fasting condition.
